1. Control elements
(23) (24)
1.1 Stereo channels 1 to 4
(1) Use the LINE/CD switch to select the input signal for channel 1.
Unlike other channels, channel 1 features two line inputs.
(2) You determine the input signals for the channels 2 to 4 with the
PHONO/CD i.e. PHONO/LINE switch (channels 3 and 4). “Phono” is intended
for connecting a turntable. “Line” i. e. “CD” must be selected for all other
signal sources (e. g. CD or MD players). The input sensitivity of the phono
input can be switched to line level, allowing utmost flexibility (see (41).)
(25) (26)
◊ Never connect devices with line level to the highly sensitive phono
inputs! The output level of phono pick-up systems is measured in
millivolts, whereas CD players and tape decks have levels measured
in volts, i.e. the level from line signals is up to 100 times higher than
that of the phono inputs.
(3) The GAIN control in the CHANNEL section is used to adjust the level
of the input signal. The level meter (5) reads the input level.
PRO MIXER DJX750 User Manual
(4) Each of the input channels features a 3-band equalizer (HI, MID and LOW)
with kill characteristic. Thus, the signal can be attenuated to a much
greater extent (-32 dB) than it can be raised (+12 dB). This function can be
very useful when, for exmple, fading a frequency range out of a music track.
◊ The overall level also depends on the EQ setting. Thus, should adjust
1.5 Crossfader section
(21) ASSIGN A and ASSIGN B selectors let you determine which input signals are
routed to CROSSFADER sides A and B. You can also alternate between these
two signals by using the CROSSFADER (see below).
(5) The 10-digit LED chains display the signal level of the input signals.
(22) The VCA controlled CROSSFADER is used to fade between the channels
you have selected (see (21)). Like the channel faders, the crossfader section
is equipped with a professional 45-mm fader.
(6) Adjust the channel volume using the CHANNEL fader.
(23) The TIME OFFSET LED indicates the synchronisation of tracks (see chapter 2.7).
1.2 Microphone channel
(24) The TEMPO DIFFERENCE LED displays tempo differences between the tracks
(see chapter 2.7).
the equalizer before setting the input gain with the GAIN control.
(7) The MIC IN connector is the balanced XLR input for your dynamic microphone.
(8) Set the volume of the microphone signal with the GAIN control in the
MIC section.
(9) There is a 3-band equalizer (HI, MID and LOW, no kill characteristic)
in the microphone section. This allows you to fine-tune your voice to
adapt perfectly to your sound.
(10) Activate the microphone channel using the MIC ON switch. The channel
is active when the corresponding LED is lit.
(11) The DJX750 is equipped with a talkover function, which works very simply:
if you speak into the microphone while a track is running, the volume of
the music is automatically reduced, so that your voice is always “in front”.
The TALK control allows you to determine how much the music volume is
lowered (max. -24 dB). This function can come in handy when your own voice
needs to be prominently heard, as in when making an announcement etc.
1.3 MONITOR section
The MONITOR signal is your headphones signal, allowing you to listen to music
without affecting the MASTER output signal.
(12) When the MODE switch is in the “Split” position, channel PFL is located
on the left side of the headphones, while the MASTER signal is on the
right side. In this case, the MIX control (see below) serves no function.
While in “Stereo” mode, you can use the MIX control to alternate
between MASTER signal and PFL.
(13) When in “Stereo” mode, the MIX control lets you determine which signal
can be heard via the headphones. When the control is turned to its left-most
position (CUE), you hear the PFL signal only; when the control is turned to
its right-most position, you hear the MASTER signal only. Alternating the
MIX control between the two end positions lets you dermine the relative
ratio between the two signals in your headphones.
(14) The Level control determines the volume of the headphones signal.
(15) Connect your headphones using the PHONES OUT stereo connector.
Your headphones should have a minimum impedance of 32 Ohms.
(16) To select the PFL signal for the headphones, use the MONITOR CUE keys
(CH-1 to CH-4, MASTER, FX). You can also select multiple signal sources
and listen to them simultaneously. LEDs on corresponding keys are lit
when a channel is routed to the headphones.
1.4 MASTER section
(17) The LEVEL METER displays the level of the MASTER signal.
(18) The MASTER fader allows you to adjust the output volume at the
MASTER output (see (44)).
(19) The MASTER BALANCE control for the MASTER output is for setting
the stereo image.
(20) The BOOTH LEVEL control adjusts the output level of the BOOTH output
(see (45)).
(25) A 3-band kill switch is available for use with both the left and the right side
of the crossfader (KILL A and KILL B respectively). Kill switches are used to
lower three separate frequency ranges (LOW, MID and HIGH) up to -32 dB.
When using the kill switch, the equalizer of ordinary DJ mixers usually
loses its functionality. Not the case with the DJX750: the EQs can be used to
achieve an even more pronounced lowering of a particular frequency range.
(26) The CF CURVE control lets you alter the control characteristic of the
crossfader between linear and logarithmic in an infinite number of
steps. When set to linear, the crossfader engages directly proportionally
to the fader’s incremental movement. When set to logarithmic,
the fader’s movement yields higher volume increases as the fader
moves farther along its range of motion.
1.6 XPQ 3D surround effect
The XPQ 3D surround function is a built-in effect that puts the finishing touch
to your music and turns every gig into a real experience. The widening of the
stereo base makes for a livelier, more transparent sound. You can determine
the intensity of the effect by using the SURROUND control (27), while the XPQ ON
switch (28) turns the XPQ effect on (the respective LED is lit).
1.7 Auto BPM counter
The integrated auto BPM counter is an extremely useful feature. It ensures
smooth transition from one track to the next, taking a lot of the guesswork out.
It can calculate the various tempos of tracks in bpm (beats per minute). Both BPM
counter sections are identical and both show the BPM value of the two signals
routed to the crossfader. The LEDs located above the DISPLAYs 1 - 4 (29) indicate
which of the four input channels are routed to the respective BPM counter.
The tempo of the track assigned by using the ASSIGN A or ASSIGN B keys is shown
in the respective Display (30). Several tempo changes in one track would produce
a constant display of various BPM values and thus lead to unnecessary confusion.
That’s why the beat counter sections each have a SYNC LOCK button (31) that can
be used during the song to limit the range of possible tempo values. This makes
sense if the counter has already calculated a realistic value. You can do the
same thing manually with the BEAT ASSIST button (32). Pushing this button at
least three times in sync with the song’s tempo results in the calculated tempo
appearing in the DISPLAY. The Beat Assist and SYNC LOCK buttons are each
equipped with a LED.
When you have limited the tempo of the tracks on both channels with the
SYNC LOCK or BEAT ASSIST buttons, the difference in tempo from both channels
is illustrated in the form of a nine-character message on the TEMPO DIFFERENCELED (24). The extent of theT difference in tempo is indicated by a corresponding
swing to the right (signal A is slower) or to the left (signal B is slower). When the
middle LED lights up, the tempi are the same. The TIME OFFSET LED (23) below that
displays the signal A and B synchronisation. Should the middle LED light up, the
tracks are synchronised. Should the display move to the left or right, the channels
are not synchronised. The TEMPO DIFFERENCE and TIME OFFSET displays are only
active if the tempi of both channels have been fixed in one of the ways described.
PRO MIXER DJX750 User Manual
◊ When no signal is present (or when the signal level is too low),
the BPM display shows only dashes. When the signal is present but
can not be identified, the display shows 160 BPM and then shows the
said dashes. The beat counter then attempts to get another readout.
Therefore, “160” BPM is no usable value; rather, it is simply an error
message when the signal can not be analyzed.
To exit the SYNC LOCK or BEAT ASSIST modes, simply push the SYNC LOCK button
once more on both channels.

2.1 Rear panel connectors
(38) These are the LINE i. e. CD inputs to connect a tape deck, CD or MD player etc.
Unlike other channels, channel 1 features two line inputs.
(39) The PHONO inputs for channels 2 to 4 are for connecting a turntable.
(40) The GND connectors ground the turntables.
(41) With the PHONO/LINE switch it is possible to switch the input sensitivity of
the PHONO inputs 2 to 4 to line level. This allows you to connect a tape deck
or a CD player to the PHONO inputs.
(44) (45) (46)
(42) (43)
The DJX750 features an internal digital effects processor into which you can
feed your master signal, the signals of the input channels or the mic signal.
The module provides a number of standard effects, such as reverb, delay and
echo, as well as various filter and modulation effects.
• To select the signal to be processed, use the SOURCE selector (33) .
• Turn the PROGRAM control (35) to select an effect. The corresponding
program number appears on the PROGRAM display (34) .
• Press and hold the PROGRAM control for about 2 seconds to load
the selected preset.
• When the new effect has been loaded, turn the PROGRAM control (35)
to change the effect’s parameters. The parameter value is shown on the display.
(42) The DJX750 features an integrated effects loop for the connection of an
external effects device. The MONITOR signal is taken at the SEND output
PRO MIXER DJX750 User Manual
and routed, for example, to a reverb processor. Thus, the signal at the
SEND connector is identical to the headphones signal and is selected with
the MONITOR CUE buttons (16).
(43) The externally processed signal is added to the MASTER output signal via the
RETURN connectors. The effect signal volume may only be adjusted at the
output control of the effects device itself.
(44) The MASTER output is for connecting to an amplifier and can be adjusted
with the MASTER fader (18).
◊ Always turn the power amps on last to avoid inrush currents that can
easily damage your speakers. And, to avoid sudden and unpleasant
surprises for your ears, make sure there is no signal at the DJX750
before turning on the power amps. To be sure, slide all the faders to
the bottom and switch all controls to the zero position.
(45) The BOOTH output gives you an additional option of connecting an amplifier
in order to, for example, feed the signal into your monitors or to bring
sound to an extra area. The BOOTH output level is regulated by using the
BOOTH LEVEL control (20) of the MASTER section.
(46) Using the TAPE output you can record your music by connecting devices
such as tape decks, DAT recorders etc. Unlike the MASTER output, the output
volume is fixed, making it necessary for you to adjust the input level on the
recording device.
(47) The POWER switch powers the DJX750 on. You should always make sure that
the POWER switch is in the “Off” position when initially connecting the unit
to the mains.
◊ Merely switching the unit off does not mean that it is fully disconnected
from the mains. When not using the unit for prolonged periods of time,
please unplug the unit’s power cord from the power outlet.
(48) This is the connector for the power cable. This is where the advantage of a
sophisticated internal power supply can be seen: the pulse behaviour of each
amplifying circuit is mainly determined by the voltage reserves available.
Each mixing console is equipped with numerous operational amplifiers
(op amps) to process line level signals. Due to limited output of their power
supplies, many mixing consoles show signs of “stress” when subjected to
heavy loads. But not your DJX750: the sound is always clear and transparent.
(49) FUSE HOLDER / VOLTAGE SETTING. Before connecting the unit to the mains,
ensure that the voltage setting matches your local voltage. Blown fuses
should only be replaced by a fuse of the same type and rating. On some
units, the fuses holder can be switched to one of two positions, i.e. 230 V
and 120 V. Please note: should you desire to operate the unit outside
Europe at 120 V, a higher fuse rating is required.
◊ To disconnect power from main, pull out the main cord plug.
When installing the product, ensure that the plug is easily accessible.
If mounting in a rack, ensure that the mains can be easily disconnected
by a plug or by an all-pole disconnect switch on or near the rack.
3. Initial Operation
◊ Ensure adequate air supply and to avoid overheating do not place the
unit near radiators etc.
◊ Before you connect your unit to the mains, please make sure that your
local voltage matches the voltage required by the unit. The fuse holder on
the mains connector has 3 triangular markings, with two of these triangles
opposing each other. The unit is set to the operating voltage printed
next to these markers and can be set to another voltage by turning the
fuse holder by 180°.
Please note that when operating the unit at 120 V, a higher fuse rating is
required. Please refer to the “Specifications” for details.
If you set the unit to a different mains voltage, be sure to use a fuse of the
correct type and rating. Please refer to the “Specifications” for details.
◊ Blown fuses must be replaced by fuses of the correct rating!
Please refer to the “Specifications” section for the applicable rating.
Before you change the fuse, switch off the device and pull the plug
to avoid electric shock or damage to the device.
The mains connection is made using the enclosed power cord and a standard
IEC receptacle. It meets all international safety certification requirements.
◊ Please make sure that all devices are properly grounded. For your own
safety, never remove or disable the ground conductors from the devices
or on the power cords. The unit must always be connected to the mains
outlet with a protective grounding connection.
◊ The sound quality may diminish within the range of powerful
broadcasting stations and high-frequency sources. Increase the
distance between the transmitter and the device and use shielded
cables for all connections.
